Hi,
Is it possible to have a surface rendered as a pure color unaffected by
light but with shadows ? Kind of like the background color but with shadows.
So if I had a plane set to color <1.0, 0.0, 0.0> it will be RGB(255, 0, 0)
everywhere except where there is shadow. I'm making 2D images of GUI
controls so this would be very useful, especially in creating the alpha
mask.
Thanks.

Your message post got added as a much older thread. Here's an idea:
finish {ambient 0 diffuse 3} // diffuse higher than 1 anyhow
That could probably do okay. Should oversaturate the color, leaving shadows
but not allowing it to lose brightness from varying lighting angles. Of
course, a plane is easier to keep uniform in color compared to other
objects.

When I create my alpha shadow masks, I use an extremely bright light
source.
